Biological Filter Design Optimization

Abstract

An optimization method is used to determine the most economical design for biological trickling filters based on four different models, the Eckenfelder, the Galler-Gotaas, the National Research Council and the Upper Mississippi and Great Lakes Board. Filter depth has the greatest influence on the most economical design with the Galler-Gotaas model, some influence in the Eckenfelder and NRC models and no influence in the Upper Mississippi and Great Lakes model.
